Increases your efficiency: The specialist with a 120-fold lifespan due to the optimized bit for T-shaped screws. Reduces your costs: The bit is quickly and easily identifiable thanks to its blue color marking, even in dark environments with UV light. Saves time: No lengthy searching thanks to the brightly colored bit and minimal bit change time due to its high durability. Application: Suitable for fastening T-shaped screws. Also compatible with impact and power screwdrivers. Additional information: Until now, there has been a lack of clarity regarding which bits are suitable for which applications. Wiha eliminates the complexity between the machine used, the screw type, and the wide selection of different bits. Thanks to Wiha's revolutionary bit concept, only the screw shape is decisive for selecting the right bit. The T-bit is therefore ideal for fastening T-shaped screws with a 90-degree angle between the thread and the screw head. With its patented extended torsion zone, the bit is also suitable for impact and power screwdrivers and has a lifespan that is 120 times longer compared to Wiha standard bits. Additionally, the colored bits are quickly and easily identifiable and can also be found in the dark with UV light thanks to the color coating. This helps reduce the number of lost bits and saves costs on replacements. DIN 3126, ISO 1173, Form C6.3. Contents: 5x T-bit 25 mm internal square 1/4.
